Pipes are made of the element Lead so the answer should be d) lead pipe
Answer:
B
Explanation:
The average kinetic energy of the Substance changes.
Answer:
Explanation:
Partial pressure of oil = mole fraction of oil x total pressure
mole fraction of oil = mole of oil / mole of water + mole of oil
= mole of oil = mass of oil / molecular weight of oil
= 20 / 100 = .2
mole of water = 80 / 18
= 4.444
mole fraction of oil = .2 / .2 + 4.444
= .2 / 4.644
Partial pressure of oil = mole fraction of oil x total pressure
= (.2 / 4.644 ) x 760 mm
= 32.73 mm Hg .
2.34 moles titanium x (6.022 x 10^23)/1 mole titanium = 1.41 x 10^24
